y To all whom #may concern Be it knownthat I, JAMES S. Mnnnnm'a" citizen ot the nited States, and resident ot' Richland, Stewart county, State ofGeorgia,

have invented certain nenY and 'useful lun proveinents 1n Methods of ,and Apparatus tor Treating; a Mixture of Cotton-Seed Meats', Hulls, and Lint, of which the following is a specification. t

This invention relates to a method and an apparatus for treating a mixture ol' cotton seed hulls, lint and meats after theyl are` passed through the helling mechanism and before oil is pressed out. i

The principal ob'ect of the invention is to make a higher grade of cotton seed meal by removing more lint and hulls :troni the iniX- ture than it is possible to screen'out.

Another iniportant object of the invention is to regulate the separationof .the hulls troni the cotton seed n'leats and to control. the protein an'damrnonia content oit the nie'al. lleretofore the ammonia and protein content ot the ineal has been controlled by putting a finer or Icoarser screen on the separating machinery, but by my system of air control any amount or all of the hulls can berenioved :troni the meats to inake the various grades ot meal Which-the market de- Inands, only a slight alteration of the air current being required.

` traine 11, which is open at the top and at its lower end." The traine 1l has a false bottoni which consists oiE a screen l2 ot per torated metal spaced above the bottom 13 of the frame, rllhe screen 12 extends the entire length of the frame ll and "projects beyond the lower end o't the bottom 13.v The frame ll is supported so that it may be given a, slight reciprocating motion byV ineens of aneccentric lt whichis connected to thebottoni of the frame 1l by the rod 15. ln order to clean the screen 122 l have provided hannners lo, which are fastened at` the ends ot a rod i7. The rodd 'i7 is piroted and at its center in brackets 1S mounted on opposite sides of the 'frame ll.. The rod is provided with an upwardly extending arm 19, which has a fixed rod 20 passing through an opening in its upper end. Springs 2l Q2 surround the rod 2O and hear against opposite sides oft' the arm i9 and against the nuts Q3 on the rod 20. `Wlien the eccen 16 will alternately, yieldingly strike the screen 12 'and prevent the clogging of the same.

` tric lll.-4 shakesthe trarne ll, the hammers rl`he miiiture of meats, hullsand lint is.

dischargedffroin the spout 524e ontothe upper end ot' the screen 1Q. te the screen is shaken the material. moves downwardly and a large proportion ot' `the finer meats will pass through the sereenl 12 onto the bottoni 13 and will be discharged throiurh the openingr at the lower end into a chute 26 which. leads to a conveyer trough orother suitable means for conveying,r the meats -to the press` ing,r mechanism.

The remainder of the material which com tains "the coarse meats,` hulls and lint Will downwaidly over the screen l2, dis-- charging through the opening 97 and `over the upper side 28 ot the air nozl/le `29. |lhis material will descend in a relatively thin and broad stream across the inlet mouth Bd of the air nozzle Eiland the current of air which is drawn upwardly into the nozzle will cross this stream of descending material and carry with it the lightermaterial, such as hulls, lint, and soine fine meats, which may not have. passed through the screen l2. |The coarser meats and sonie of thehulls descend into the chute 26 tobe mixed with the iine meats which passed through the ti ii In order to vvary the protein and. annnonia4 content of the meats sent to the press room, the air pressure may he altered by rneans of a slide 3ft which regulates thc-size of an opening' in the air `pipe changing' the site ol. the opening,r controlled by the slide Seimthe lifting power ot the air By merely I current may be 'variedwithin a .wide redigev 11o m we and any desired/gracleci material may he delivered lo the oil presses.

Ilhe meats may then he delivered by e sniseperated Vfrom the hulls and; lintn able conveyer to the oil presses.

From the foregoing description it will be seen that l have provided a simple mecha nism by means of which the inears may be The meats are more thoroughly separate@ from the hulls by this mechanism enel therefore the capacity of ythe press room .is consiclerably increased because .the presses which formerly operated upon a more inccxnpletely separaed mixture of hulls, lint and meals may now he nsecl on'meats which nre nearly entirelyfree of hulls and lini.. .The arrangement herein disclosed also provides for a simpler control of ihe protein'v and ammonia content of the meal. By e simple airliner ment of the slide 34' any grade olf nnierial maybe provided for ille oil presses.

While l here shown and described the in- 'vention in (letali l do not Wish to ce limited to the exact form' of mechanism illnsiraterl as it will ce obvious that numerous changes may be mede in details Without deparlting from che principles ci the invention. Having thus described the izn'eniin11,wln\t is claimed and desired to be secured by Letters Patenll is:
